HESI A2 Vocabulary 2023

Correct Answer: A

Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.

Correct Answer: A

Rationale: The correct answer is A: Bogus. 'Spurious' means not genuine or false, which aligns with 'bogus.' The sentence suggests the researcher made a misleading or false argument. Choice B, obscure, means unclear or hard to understand, which doesn't fit the context. Choice C, baffling, means confusing or perplexing, but doesn't capture the deceitful nature of 'spurious.' Choice D, outrageous, means shocking or offensive, which is not the same as being false or deceptive. Therefore, 'bogus' is the best fit for the context of the sentence.

Correct Answer: D

Rationale: The correct answer is D: Bond. Rapport refers to a close and harmonious relationship or connection between individuals. In the context of the sentence, 'developed a quick rapport' implies that the nurses and teenage aides quickly formed a close bond or connection. This is evident through their ability to communicate effectively, trust each other, and work well together. Choice A: Performance is incorrect because rapport does not refer to performance but rather the relationship between individuals. Choice B: Narrative is incorrect because rapport does not relate to storytelling but rather the bond or connection between people. Choice C: Manner is incorrect because rapport is not about the way something is done but rather the quality of the relationship. In summary, the word 'rapport' in this sentence specifically means a bond or connection between the nurses and teenage aides, making choice D the correct answer.

Correct Answer: A

Rationale: The correct answer is A: Collection. A compendium refers to a concise collection of information or knowledge on a specific subject. It is a comprehensive summary or compilation. "Aptitude" refers to a natural ability or talent, not related to a compendium. "Conclusion" refers to the end or result of an argument or discussion, not synonymous with compendium. "Humor" refers to the quality of being amusing or comic, which is unrelated to the concept of a compendium. Therefore, A is the most appropriate synonym for compendium in this context.

Correct Answer: B

Rationale: The correct answer is B: Ulnar nerve. The "funny bone" is a term used to describe the ulnar nerve that runs along the inside of the elbow. When this nerve is bumped, it can cause a tingling or funny sensation. The ulnar nerve is not a bone, ruling out choices A and C. Choice D, biceps brachii, is a muscle in the arm and is not related to the "funny bone" sensation.
